It comprises a rack-shaft (2) to be coupled to the guiding wheels of a vehicle, a housing (A) for slidably containing the rack-shaft (2) and holding therein a coupling section (6) for causing the teeth of the rack-shaft (2) to engage those of a pinion arranged on the steering column (5) linked to the steering handle of the vehicle and an electric motor (1) coaxially arranged around the rack-shaft (2), whose rotary force is transmitted to the rack-shaft (2) by way of a ball screw mechanism (3) as the steering assisting power. It further comprises another housing (B), for rotatably supporting the nut section of the ball-and-screw mechanism (3), said housing (B) being provided with a fitting section to be secured to the vehicle main body. The housing (A) is secured to the vehicle main body by means of a bracket (9), while the housing (B) is secured to the vehicle main body by means of a fitting section (10). <IMAGE>
